QUICK-CHANGE MACHINE.

To all whom 'it may concern.:

Be it known that I, Moms A. BARR, a

citizen of the United States, residing at Ardmore, in the county of Montgomery and State of Pennsylvania, have invented certain new and useful Improvements in Quick- Change Machines, of which the following is a specification, reference being had to the accompanying drawings. I

This invention relates to means for dispensing coins and particularly to means for dispensing coins for change. v

The general object of this invention is to provide a very simple, readily operated and Specification of Letters Patent.

f Application filed April 30, 1917. Serial No. 165,428. A

' ever, being broken away at its rear end and eifective machine of this character whereby coins from a stack of coins may be discharged onto a table at the will of theA operator, means being provided on the table whereby a proper number of coins 'may be withdrawn from the table according to the amount desired by the operator.

A further object of the invention is to provide a machine ofthis character including a coin receiving table and a reciprocable coin holder movable over the face of the table and holding a stack of coins, the ar' rangement being such that on a rearward movement of the c'oin holder, a series of coins will be laid flat down upon the table, one behind the other and upon a forward movement of the holder, the coins will be v pushed forward so as to again ll up the table.

A further object of the invention in this connection is to provide means for preventing the superposition of onev coin upon another as the coin holder is moved rearward, said means being preferably adjustable, so that the machine may be used with coins of different thicknesses and did'erent values.

A further object is to provide adjustable means, which will engage the rearmost coin of a line of coins, so that when the holder y is moved forward, the lowermost coin of the stack of coins will be carried forward with the helder so as to be left at the forward or discharge end of the table.

Other objects will appear in the course of the following description.

My invention is illustrated in the accompanying drawings, wherein z- Figure 1 is a. longitudinal sectional view of a coin dispensing apparatus of the character described, the section being taken on the line 1-1 of Fig. 2, the coin holder, howbeing partly in section; Y

Fig. ,2 is a top plan view `of the construction illustrated in Fig. 1;

Fig. 3 is a fragmentary sectional view on the line 3-3 of Fig. 1 looking in the direction of the arrows.

Referring to these drawings, 10 designates a base or table of any suitable dimensions, and which is provided at spaced intervals with the longitudinally extending guide walls 11, defining coinways 12. These guide walls are spaced at diii'erent distances from each other so that the guideways will have dierent widths, according to the denomination of the coins to be discharged. I have illustrated in the drawings, the base as formed with four guideways, a, b, c and d, it being understood, however, that a greater number of guideways may be used or a less number. The guideway a is illustrated as holding pennies, vthe guideway t Vas holding five cent pieces, the guideway c as holding ten cent pieces, and the guideway d as holding twenty-five cent pieces.4 This, of course, is purely illustrative. Each of the walls 11 is provided'with inwardly extending grooves 13 on its opposite faces and at the rear end of the base there is provided the transversely extending wall 14 and the longitudinally extending side walls 1:5, the rear wall being illustrated as mounted upon the rearwardly projecting ends of the guide stri-ps 11. At the forward end of the table 10, opposite each guideway, there is provided a button 16, which, when turned to a vertical position, prevents the discharge of coins from the gnideway, but which when turned into a horizontal position permits such discharge.

operatively supported in connection with each guideway a, I), c or d, is a coin holder. These coin holders are all alike in construction. Each holder is designated 1T. Each holder is formed at the bottom odge with a transversely extending plato 1S, which is adapted to engage in the grooves 13 of the guide strips 11. Each holder at its lower end is reduced in width so as to tra vol be-n tween the guide strips and above the guido strips rests upon the upper faces of the strips. as illustrated best in Fig. 3. These coin holders 17 are adapted to be reciprocated along the guideways. and preferabli the upwardly and rearwardly inclined face pin'having anick Y the screwpin may i' 20 of each lh'older'is formed'f with a stud, button or handle 19, whereby the holder may be reciprocated.' v Y Y Each holder adjacent' its rear end -is formed with a coin receiving` chamber 20. vertically disposed and open at its top and bottoni, this chamberbemg of a size suitable to receive the particular/coins disposed 1n the holder, but permits said coins to move downward gravity. The ,plate 18 is, of course, also formedV withan 'opening 21 beneath the chamber 20-thrcugh which the coins are discharged. The coins are stacked one upon another within the chamber 2O and fed downward therethrough by gravity. ,Disposed rearward of the chamber 20 is as stop 22 illustrated as in the form of a screw at its lower end so that be adjusted. The screw pin is soy adjusted that its lower end is just above the upper face of the table or base 10 but extends down below the upper face of the lowermost coin of the stack of'coins. Immediately in advance of there is provided an adjustable stoppin 23, which is also screw-threaded and nicked at its lower end' so that it may be adjusted and thisscrew pinjs so adjustedth'at it will escape the lowermost ,coin of the stack of coins. As illi1strated,.1.'thc plate 18v is spaced from the upperface o the table 10 a distance equalto two coinsand hence the necessity o this 'pin 23. If the coins are thick, this pin 23 may ,bey adjusted upward so as to increase the distance between thekpin 23l and the face of the table 1() and if the coins are relatively thin,A the pin may be', adjusted downward to decrease the distance between the lower end of the pin and the table 10, in a manner which will be obvious It will be seen, of course, that the cross bar 14 forms alstop limiting the rearward movement'of the variousV coin holders.

I In order to indicate to an operator' the amount 'of .'coinsdesired vto make change,

' certain Vof the longitudinally extending strips- .11. are vprovidedl with gra'duations. f Thus l'the lOngitudi-nalstrip 11 which ditween the numeral lguideway.y there are 10 pennies.

vides the guideway' a--from the guideway is provided with' numerals 5 and 10 spaced from each other and with arrows pointing and it will be seen the end of are 5 pennies andbe- 10 and the'end ofthe The guide the guideway, there k,strip y11 which-divides the guideways c and 's'pointmg to 'fprovided with the 7 "from each other has arro numerals y25 and 50'and'it will .be seen that `there areiive '5 lcent lpieces the'end vci' the-i guideway {25ar1`d tenk 5"' cent fpieces 'the' endof theguideway and thelnumeral sposed between and the numeral vdisposed between 50. The strip which divides the guidethe chamber 20 f worthv of f ward until the vacant space -from the drawing.

'device may discharge of coins, and a coin a imma@ 'guiaeway dasprovidedA Frith 4In the operation of this device,

that the guideways arey all empty, then onel of the holders 17 shifted forward, the corresponding button 16 being turned to perm-it thisl movement,. and the pin 21 will slide the lowermost. coinofthe series of coins in the stack forwardwith the holder.' Then when the holder is. rshiftedvv rearward coins will drop-one after theother onto the table, the pin 23 preventing asuperposition of the coins and when'theholder has'been shifted to itsrearmostposition, there will be aline ofcoins disposed oneafter the other along the face of the. guideway, in the manner. illustrated in Fig. l 1. The same operation is performed with all of' the holders until all the guideways are filled.

wherein are disposed AN ow when itis desiredv to make change or'- 'dispense a certain number4 of coins, the button on the particular guideway is turned down and coins are drawn. out by hand, according tothe graduation marks `on, the guideways. Assuming that twenty-tive cents ive cent pieces have been withdrawnfro'm the guideway b, then the oper. guideway forator shifts the holder of that has been lfilled and then shifts theholder back to itsrearmost position when the guideway will yagain be entirely filled with coins. As fast as the coins are exhausted from'the chambers 20,

new coins maybe disposed in these chambers. As illustrated,

through the top thereof. each holder and guideway together vwill accommodate about 50 coins, but it isobvious' that this capacity may be changed. It is,l of course, obvious that this coin dispensing be made to hold'dollars, ive dollar gold pieces, etc.
